The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern .-1

Be it known that I, JAMES S. WETHERBY, of the city,.county, and State ofNew York, have invented certain novel and useful Improvements in theGonst-ruction of Fluid-lamp Burners; and I hereby declare the followingto be a full, clear, and exact description thereof, reference being hadtol the accompanying drawings, which are lettered to correspond with andform a part, of the specification.

To enablethe public'to understand the nature of my said invention, andto enable those who are skilled in the mechanic arts to construct thesame,'I will describe it as follows, to wit:

Figure 1 is an exterior viewof my metallic cone A, which surrounds andprotects the dame.

This conical cap is made of any suitable sheet metal, and covered with amineral jacket, such as china, porcelain, or other similar coating, andis also provided with four standards or upright arms, 1 2 3 4, which aresecured to the outer periphery of the base of the cone A for the purposeof holding the glass chimney in its place from the outer side, in lieuof having the standard on the inside of the chimney, as heretoforeemployed.

Figure 2 is a vertical section of fig. 1, showing the inner perforatedcone P'I, which forms a part of the tube U of the wick-holder or tube BB, which is provided with a hook, H, at its lower end or base,thatscrews into the lamp.

Figure 3 is a perspective drawing of the wick-holder, B, and a sectionof its cuter tube C and hook H, which suspends the burner or wick-holderB upon the side of the lamp, Without takingy the wick VV out of the lampduring the process of filling the same.

By the construction of a double conical cap, A, having the inner cone PP perforated s o that a free upward current of cold air passes aroundthe tube O of the wick-holder or burner B B, I am enabled to keep thelamp perfectly cool. Hence, it is less liable to explosion,and theconical cap A is lifted off of the lamp, while trimming the wick,without unscrewing the burner B from the lamp; and when it is requiredto replenish the lamp with kerosene, or other Huid, you simply unscrewthe burner B and hook the hooked end H upon the edge of the throat ofthe'lamp, while the wick W is suspended in the same Vduring the op-`cheaply constructed of the coarser metals, (such as tinned iron,) atasmall expense.

Hence, the novelty of my invention consists in the construction of adouble cone, A, and PP, having a mineral covering of porcelain, china,or their equivalent, and being provided with any suitable number' ofarms, 1 2 3 4, upon the outside of the chimney, and having the innercone P I perforated, and so constructed as to constitute a part of thetube C that fits over the .wick-holder or burner B B, which is providedwith a hook, H, for convenience, and a more safe arrangement whiletrimming and filling the lamp, which is kept perfectly cool by means ofthe conical air-Hue P P. Therefore What I claim as new and useful, andwhat I wish to secure by Letters Patent of the United States, is

The cone A, with porcelain or other earthen covering, and innerperforated conical jacket P P, provided with tube C to hold thewick-'holder or burner B, and standards or arms 1 2 3 4 on the outsideof the chimney, and hook H, all arranged and operating in the manner andfor the purpose set forth and shown in the accompanying drawings.

In testimony whereof I hereunto subscribe my name in the presence of twowitnesses.
